My question is pretty simple, is there anything more to LAN than just basic internet connection I get when buying a plan from an internet provider? Thanks

The LAN is Local Area Network.
Basically inside your house or business.

ISP->Modem/router->2 PC's.
The 2 PC's and part of the router a "LAN".

The ISP is just concerned about what happens outside your house, and up to the 'modem'.

And you can have a LAN with no service from an ISP at all. It will just allow comms between local systems, but it is a LAN.
Local.

I'm not sure I understand the question, but:
LAN is your home network, it allows your local devices to communicate with each other. You pay your internet provide to connect your LAN with the internet (WAN). You can have a LAN with no internet connection, and you can have a WAN connection with no LAN (i.e. a single device plugged a modem).
